As is well known to those having experience in launching automobiletorpedoes or dummy torpedoes, either in actual warfare or in targetpractice, that owing to various causes, such as rough seas or faultysteering gear, they often deviate from their course, and with automobiletorpedoes while they run very accurately at'high speeds, at low speedsthey are uncontrollable and erratic, and often through fault in thefunctioning of the horizontal rudder they plunge toward and embed theirnose into the bottom into which they stick, and, in consequence arelost, .and unless they do sink to the bottom, they are dangerous tonavigation since they usually float immediately below the surface. `Withthe .use of my attachment, however, after the torpedo or dummy strikesthe water the Water will enter the reservoir and iioat the oil to thesurface, which owing to its specific gravity, will immediately rise toand spread upon the waters surface in small patches thus indicating tothose in surface vessel the course the torpedo or dummy has taken, andin the event of its plunging into the bottom, or when its momentum islost, the oil. will continue to escape from the reservoir and form alarge oily surface in the immediate vicinity of its resting place to'thereby indicate its locality and consequently to facilitate itsrecovery.

lVliile I have shown and described my attachment for use in connectionwith automobile torpedoes or dummy torpedoes, l do `not wish to beunderstood as confining myself to these uses as it Will `be understoodthat the attachment may be used with equal effectiveness on submarineboats especially `or when operating in connection with a l' 1 parentsurface vessel or a fleet. ltspecially wouldmy attachment be serviceableon submarine vessels when operating with a fleet of surface ri-'esselsinrough weather since, in

.very rough weather, the siibinarines-niay be operated subii'ie'rgedandcaused to travel m .advance of the surface fleet and by emitting theVoil lfrom the reservoirs they `not only V providea n'ieansforindicatingto those on I 50 boardftli'e surface vessels, their appro.\ i.iiiatelocality and the course they are running, but also the additionalpurpose of spreading oil upon the troubled .waters to smooth the sur--faces and thus` facilitate lthe progress of the surface vessels.

I'i'm aware that mechanical devices have been 4c-,iiiploy'fedinconnection with autoniebile vtorpedoesand dummy torpedoes forA givingthem positive buoyancy .and causing` them to rise to the surface in theevent of their sinking below a certain depth through faulty action oftheir horizontal rudders or other mechanically operated parts, but thesedevices are expensive and owing to their location are ineffectiveespecially should the torpedo or dummy take a downward course and stickits nose into the bottom of the Water-bed, and I make no claim to adevice for regulating the buoyancy of the vessel or for causing it tofloat upon the surface after its propelling mechanism or iots initialpropulsive force has been spent,

What l do claim and desire to secure by Letters Patent is,

l. The combination with a vessel adapted to travel beneath the surfaceof the Water and having a chamber therein, and of means carried Withinthe said chamber and adapted to escape therefrom for indicating` thecourse or final resting place of the said vessel below the surface ofthe Water.

2. An attachment for vesselsadapted travel beneath the surface of theWater, comprising an oil reservoir arranged `Within the vessel and opento. the surrounding. body of- 'ivater, whereby tov permit Water to4enter said reservoir and the oil to be loatedfthere'- from when thevessel is submerged-mhp stantially asl SPGcified.

3. An attachment for automobile or dummy` torpedoes, comprising anv oilreservoirar-V ranged Within the vessel, and oil outlet ex` tendingtherefrom and opening into the surrounding body of Water, and a waterinlet leading to said reservoir from the surrounding body of Water. 'l

Il. An attachn'icnt forv vessels' adapted to travel beneath the surfaceof the water, comp rising -an oil reservoir arranged "Within vthevessel, and a valve-controlled outletleading from said reservoir andopening through i the skin of the vessel.' i
